A sound knowledge of the relative three dimensional (3D) approximations to the inferior alveolar nerve (IAN) to the root apices of the mandibular premolars and molars and their significance to gender and age is imperative for any dental procedure. Utilization of Cone Beam Computed Tomography (CBCT...
No statistical significance between two observers with regard to the data about the thickness of lingual plate as well as the distance between root apex and lingual plate in randomly selected cases was observed (P > 0.05, Student-t test, Supplementary Table 1 and data not shown). More...
Roots can be classified into three main types: primary, secondary (see LATERAL ROOT), and ADVENTITIOUS (1). The primary root of ANGIOSPERMS develops from the radicle of the seedling. Later, secondary roots emerge from the top of the primary root and then further down. At the apex of the ...

Most nitrates are stored in the head and apex of the root, more in the axial cylinder than in the primary cortex. The content of both compounds is higher in the superficial layers of some root vegetables, e.g., beetroot, than in the central parts. Such a relationship does not exist in...
We detected the presence of amyloplasts in the root cap zone of Ceratopteris, and low signal was also observed within the root apex (Figure 3F). Amyloplasts have been found in other ferns, in the root cap of Regnellidium diphyllum and in the stele of A. filiculoides roots [60,85]...
Brassinosteroid (BR) signalling regulates cell length and meristematic cell counts in the root in both the longitudinal and radial axes10,11. The signalling is initiated upon binding of the hormone to its cell surface receptor, BRI1, through a regulatory sequence involving the inactivation of the ...
Effect of Combined Use of Photon-Initiated Photoacoustic Streaming and Chitosan on Smear Layer Removal Because the apical foramen may not correspond to the anatomic root apex, but may be coronal to it, as the course of resorption progresses, it is advisable to maintain a working length 2-3 mm...
